These comprehensive set of concepts forms a strong foundation for programmers, covering a range of skills from programming fundamentals to system design and security considerations.

1. Introduction to Programming Languages: A foundational understanding of at least one programming language (e.g., Python, Java, C++), enabling the ability to comprehend and switch between languages as needed.

2. Data Structures Mastery: Proficiency in fundamental data structures such as arrays, linked lists, stacks, queues, trees, and graphs, essential for effective algorithmic problem solving.

3. Algorithms Proficiency: Familiarity with common algorithms and problem solving techniques, including sorting, searching, and dynamic programming, to optimise code efficiency. ** 4. Database Systems Knowledge:** Understanding of database systems, covering relational databases (e.g., SQL) and NoSQL databases (e.g., MongoDB), crucial for efficient data storage and retrieval.

5. Version Control Mastery: Proficiency with version control systems like Git, encompassing skills in branching, merging, and collaboration workflows for effective team development.

6. Agile Methodology Understanding: Knowledge of the Agile Software Development Life Cycle (Agile SDLC) principles, emphasizing iterative development, Scrum, and Kanban for adaptable project management.

7. Web Development Basics (Networking): Fundamental understanding of networking concepts, including protocols, IP addressing, and HTTP, essential for web development and communication between systems.

8. APIs (Application Programming Interfaces) Expertise: Understanding how to use and create APIs, critical for integrating different software systems and enabling seamless communication between applications.

9. Testing and Debugging Skills: Proficiency in testing methodologies, unit testing, and debugging techniques to ensure code quality and identify and fix errors effectively.

10. Design Patterns Familiarity: Knowledge of common design patterns in object-oriented programming, aiding in solving recurring design problems and enhancing code maintainability.

11. System Design Principles: Understanding of system design, including architectural patterns, scalability, and reliability, to create robust and efficient software systems.

12. Security Awareness: Fundamental knowledge of security principles, including encryption, authentication, and best practices for securing applications and data.

Other areas could be OS, containers, concurrency and parallelism , basic web development etc.

Git Merge vs. Rebase vs. Squash Commit! What are the differences?

When we 𝐦𝐞𝐫𝐠𝐞 𝐜𝐡𝐚𝐧𝐠𝐞𝐬 from one Git branch to another, we can use ‘git merge’ or ‘git rebase’. The diagram above shows how the two commands work.

This creates a new commit G’ in the main branch. G’ ties the histories of both main and feature branches. Git merge is 𝐧𝐨𝐧-𝐝𝐞𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐯𝐞. Neither the main nor the feature branch is changed.

Git rebase moves the feature branch histories to the head of the main branch. It creates new commits E’, F’, and G’ for each commit in the feature branch.

The benefit of rebase is that it has 𝐥𝐢𝐧𝐞𝐚𝐫 𝐜𝐨𝐦𝐦𝐢𝐭 𝐡𝐢𝐬𝐭𝐨𝐫𝐲.

Rebase can be dangerous if “the golden rule of git rebase” is not followed.
